Variable Adjustment Methods for Hemihamate Autograft Arthroplasty in Proximal Interphalangeal Joint Fracture/Dislocations: A Surgical Technique Revisited and Case Series.

ABSTRACT: Proximal interphalangeal joint fracture/dislocations, even after surgical correction, often lead to long-term complications including posttraumatic arthritis, prolonged joint stiffness, and chronic joint instability. A wide range of surgical techniques has been devised to resolve this issue, but none has been promising enough. Despite this circumstance, arthroplasty using a hemihamate autograft of size and contour that match the middle phalangeal base has progressed into one of more acceptable methods that provide both articular congruency and osseous stability. In this article, we introduce various types of proximal interphalangeal joint fracture/dislocations and individualized surgical approach using hemihamate autograft and lag screw and/or hook plate as fixation methods.
